When should high-frequency ventilation be considered?
Answer
High-frequency ventilation should be considered in various clinical scenarios, particularly when conventional ventilation settings become excessive or potentially harmful.
Excessive Conventional Ventilation: When conventional settings require very high peak inspiratory pressures and plateau pressures (≥ 30-35 cmH2O) and the patient's pH remains below 7.1, indicating significant acidosis.
Avoiding Ventilator-Induced Lung Injury (VILI): High-frequency ventilation helps reduce alveolar damage caused by large positive pressure swings, providing a safer alternative to conventional methods.
Lung Recruitment and Prophylactic Use: It is beneficial for lung recruitment in cases like Acute Respiratory Distress Syndrome (ARDS) and is used prophylactically in extremely low birth weight neonates or infants born before 26 weeks gestation.
Specific Conditions: High-frequency ventilation is also indicated for patients with air leak syndrome, meconium aspiration, persistent pulmonary hypertension (PPHN), and pediatric ARDS.
By mitigating the risks associated with conventional ventilation and providing targeted respiratory support, high-frequency ventilation plays a crucial role in managing critically ill patients in the NICU and PICU settings.

She started her career at Nemours Children's Health in Wilmington, Delaware, where she joined the CMO and Cardiac OR team and then became the PICU Clinical Lead. In her role as the PICU Lead, she enjoyed providing education not only to RTs but to nurses and physicians as well on mechanical ventilation and other Respiratory topics. Her love of educating and research landed her the current role of Clinical Instructor and Research Coordinator. Since in this role, Kelly has submitted over 30 abstracts to the AARC as well as multiple manuscripts. Kelly also enjoys volunteering her time presenting talks with ICON Academy and at AARC Congress and providing care during medical mission trips to Nigeria.
